A) x + y = -7
B) x * y = 3
y = 3/x then put this into equation A
x + 3/x = -7
x^2 + 3 = -7x
x^2 +7x + 3 = 0
x = -6.5414 and x = -0.45862

In five minutes, you observe that the angle of elevation of a hot air balloon, climbing vertically, changes from 25° to 60°. If
Anna71 [15]

Answer:

379.72 meters

Step-by-step explanation:

At first, the balloon was 300 m away at 25°, so its height can be determined as:

H_{1} = 300*tg(25)\\H_{1} = 139.89 m

After 5 minutes, the balloon was at 60°, so its height can be determined as:

H_{2} = 300*tg(60)\\H_{1} = 519.61 m

To find the distance traveled by the balloon during that period, simply subtract the second height by the first one:

d= H_{2} -H_{1} \\D= 519.61 - 139.89 \\D=379.72

The balloon traveled 379.72 meters in that time.

27 - 10 = 17

The answer would be 17/30
